Details of electrical data can be found on the rating plate, which also
includes the model identification number and serial number which are
required for the ordering of spare parts.
2 Safety
Our side-channel blowers excel by a high degree of operating safety.
As the side-channel blowers are rather high-powered machines, the
safety instructions must be strictly adhered to in order to avoid
injuries, damage to objects and to the machine itself.
2.1Suction effect
Side-channel blowers produce a powerful suction effect.
Warning
Objects, items of clothing and also hair can be
sucked Into the intake port.
Danger of injury!
Do not stand near the intake opening during
operation.
Never operate the side-channel blower with open
Intake port. The open intake port must be covered
with a wire guard in accordance with DIN EN 294.
Do not reach into intake opening.
2.2Blowing effect
Warning
Powerful blow-out at the discharge flange. Sucked' In objects
may be ejected at very high speed (danger of injury).
Side-channel blowers are meant for conveying clean air only.
The sucking-in of solid particles and other contaminants - which
might be discharged - must be avoided at all times. These
objects have to be withheld before entering into the side-channel
blower by installing a filter. The side-channel blower may never
be operated with open discharge flange, and therefore has to be
protected with a wire guard in accordance with DIN EN 294. Do
not reach into the discharge opening.
2.3Temperature
Warning
The blower housing heats up during operation. If the
temperature exceeds +50° C, the side-channel blower must be
protected by the operator against direct contact (danger of
burning!).
2.4Motor circuit breaker
Before starting operation of the side-channel blower, the drive motor
has to be safeguarded by a motor circuit-breaker.
2.5Proper application
The side-channel blowers are designed for conveying clean air only.
Using them for
• aggressive
• poisonous
•explosive or
• very moist
media is not permitted.
The maximum permissible temperature of the conveyed medium for
the standard version is -30° C to +40° C. Solid particles or
contaminants must be withheld by a filter unit before entering the
side-channel blower.
The maximum ambient temperature must not exceed +40° C, the
minimum not below -20° C.
The side-channel blower cannot be operated in an explosive
atmosphere.
Special versions for applications not mentioned above are
available on demand.
Remodelling and modifications of the side-channel blower are not
allowed.
2.6Generation of noise
The noise generated by the side-channel blower is not constant over
the whole performance curve (see diagrams below).
In certain unfavourable cases a sound-absorbing device may be
required (measurements by the operator are recommended).
Sound-absorbing measures are to be carried out by the operator so
as not to exceed the legally permitted peak values at the work places
near of the side-channel blower.
3 Installation
3.1Transport
•Check all parts for damage during transport before installation and
starting of operation.
• Do not store the side-channel blower unprotected in the open
(protect against moisture).
• Attach hoist securely. Only use hoists and load suspension
devices with sufficient load-carrying capacity.
3.2Installation, assembly
• Install side-channel blower horizontally or vertically and
weather-protected.
• Do not subject to vibrations or shocks.
• Side-channel blower with base; to be secured tightly at site of
operation on solid, even ground.
•Side-channel blowers, which are placed on existing rubber
elements, must be secured against twisting.
• Open intake and discharge ports are to be protected by wire
guards in accordance with DIN EN 294.
• Ensure adequate motor cooling, max. ambient temperature
+40° C.

3.3Electrical connection
Note!
The work described under this section may be
executed by a qualified electrician only. Connections
to be carried out in accordance with wiring diagram
in terminal box and relevant local regulations.
As drive motor for the SD blower a three phase a.c. motor is fitted,
the SE blower with a single phase a.c. motor with operating
capacitor.
• The drive motor has to be safeguarded by a motor circuit-breaker.
• The safety earth terminal can be found in the terminal box.
3.3.1 Connection for three phase units
- configuration
(lower voltage)
- configuration
(higher voltage)
Checking direction of rotation
Start operation of side-channel blower. The direction of rotation of the
impeller must correspond to the directional arrow on the housing. The
flow direction of the air flow must also correspond to the directional
arrows on the muffler housing. If the direction of rotation is incorrect,
the two connecting wires L1 and L3 have to be interchanged.
3.3.2 Connection for single phase units
Anti clockwise
4 Operation
If the rated current of the drive motor is exceeded during operation,
the voltage and frequency of the power supply should be checked
and compared with the data on the unit rating plate.
For side-channel blowers which cannot be operated over the whole
range of the characteristic curve, an overload of the motor may occur
in case of excessive system resistance (excessive current
consumption). Should it not be possible to exclude overloading due to
the system resistance, a pressure control valve must be provided on
the suction or pressure side.
The side-channel blower must not be subjected to vibration or shock
loads.
5 Maintenance
Repairs must be carried out by the manufacturer only. We cannot
accept any liability for repairs carried out by third parties.
